Partitions being mounted in fc8

I looked in /var/run/PolicyKit and it is empty.
I ran the polkit-grant --delete donvogt and rebooted.
The partitions are still mounted.
 I think Mar 26 was the day I installed fc8 from the
liveCD and did "yum update". If I gave me that
privilege, I don't remember (not at all surprising).
 I guess I can add a "cd /media"  "sudo umount *" to
rc.local or somewhere. Not very elegant, but so far I
can't find any comprehensible (for a user)
documentation on where or how this stuff is
controlled.
In /etc/PolicyKit/PolicyKit.conf, I have

<config version="0.1">
 <match user="donvogt">
              <return result="yes"/>
 </match>
</config>
  
Which I got out of the manual. I suspect that has the
effect of turning off whatever controls PolicyKit is
trying to control. In my case that may be OK since I
am the only user (until I get rootkited).
 Thanks for the help.
